解读病毒性传染病的六大特点   总被引:1,自引:0,他引:1  
病毒性传染病具有普遍性、依赖性、适应性、恶毒性、顽固性和难预防等六大特点.病毒性传染病分布广泛,种类繁多,病毒可以引起全身各个组织器官的病变;病毒必须依赖于宿主细胞,在其中复制和增殖,病毒具有"嗜袭性",进入人体后,各得其所,赖以生存.病毒具有高度变异性,变异株可以适应各种环境,有益于自身的延续;病毒可以引起全身各系统的病变,其中对于中枢神经系统的损害往往是致命性的;病毒具有不同的变种,随时可能发生不同的变异,难以研制出普遍有效的疫苗.  相似文献

This study assessed the psychometric properties of a parent-reported tic severity measure, the Parent Tic Questionnaire (PTQ), and used the scale to establish guidelines for delineating clinically significant tic treatment response. Participants were 126 children ages 9 to 17 who participated in a randomized controlled trial of Comprehensive Behavioral Intervention for Tics (CBIT). Tic severity was assessed using the Yale Global Tic Severity Scale (YGTSS), Hopkins Motor/Vocal Tic Scale (HMVTS) and PTQ; positive treatment response was defined by a score of 1 (very much improved) or 2 (much improved) on the Clinical Global Impressions – Improvement (CGI-I) scale. Cronbach’s alpha and intraclass correlations (ICC) assessed internal consistency and test-retest reliability, with correlations evaluating validity. Receiver- and Quality-Receiver Operating Characteristic analyses assessed the efficiency of percent and raw-reduction cutoffs associated with positive treatment response. The PTQ demonstrated good internal consistency (α = 0.80 to 0.86), excellent test-retest reliability (ICC = .84 to .89), good convergent validity with the YGTSS and HM/VTS, and good discriminant validity from hyperactive, obsessive-compulsive, and externalizing (i.e., aggression and rule-breaking) symptoms. A 55% reduction and 10-point decrease in PTQ Total score were optimal for defining positive treatment response. Findings help standardize tic assessment and provide clinicians with greater clarity in determining clinically meaningful tic symptom change during treatment.  相似文献

与传统工业经济相比,网络经济具有信息网络所赋予的新的特点,同时又蕴藏着特定的道德内涵。从网络经济的特征的视角来看,我们可以发现网络经济中所蕴藏的“以人为本”、“服务顾客”的道德取向;合作双赢、利益共享的伦理理念;公正平等、和谐共处的价值导向;开放自由、共同发展的伦理方向。  相似文献

考察云南省中、小学生师生关系的发展趋势、类型特点和师生关系对中小学生学校适应的作用.采用分层随机取样的方式选取云南省中小学生9055名,调查了他们的师生关系和学校适应.结果发现:(1)云南省中小学生与教师的依恋和亲密性随年级升高呈下降趋势,冲突和回避性随年级升高呈先上升后下降趋势,初中生得分最高.不同年级段学生和性别之间存在显著差异;(2)云南省中小学生与教师的关系存在三种类型:矛盾型、疏远型和亲密型.在矛盾型分布上,随年级升高呈先上升后下降趋势,初中生矛盾型最多.在疏远型上,随年级升高呈上升趋势,高中生疏远型最多.在亲密型上,随年级升高呈下降趋势,小学生亲密型最多.在三种类型上,小学和初中年级段学生存在显著性别差异;(3)冲突性和亲密性是中小学生学校适应的重要预测变量,回避性对中学生有显著预测作用.(4)具有亲密型师生关系的学生学校适应能力显著好于矛盾型和疏远型.结论:应加强对学生亲密型师生关系的培养,更加重视对中学生师生关系的干预.  相似文献

652名大学生应对方式与其人格特质的相关研究   总被引:1,自引:0,他引:1  
对682名在校大学生同时进行“应对方式问卷”和“16PF”测试,并对652份有效答卷进行了数据处理。结果发现,大学生在认知、情感、行为三个方面所表现的积极与消极的应对方式与其所反映的16种人格特质之间存在不同程度的相关,尤其是与C(稳定性)、H(敢为性)、O(忧虑性)、Q3(自律性)、Q4(紧张性)这些人格特质均存在非常显著的相关,而与B(聪慧性)、I(敏感性)等人格特质仅在个别侧面有显著相关。经过二次因素分析发现,大学生的认知、情感、行为方面的应对方式与其次元人格因素也存在着不同程度的相关。  相似文献

We investigated the distinction between traits (also labelled basic tendencies or dispositions) and (characteristic) adaptations, two related features of the personality system postulated to influence how personality manifests throughout the lifespan. Traits are alleged to be universal, causal, and enduring entities that exist across cultures and through evolutionary time, whereas learned adaptations are acquired through sustained interaction with cultural, physical, and social environments. Although this distinction is central to several personality theories, they provide few measurable criteria to distinguish between traits and adaptations. Moreover, little research has endeavoured to operationalize it, let alone test it empirically. Drawing on insights from four frameworks—the Five-Factor Theory, Cybernetic Big Five Theory, Disposition–Adaptation–Environment Model, and New Big Five—we attempted to investigate the distinction both theoretically and empirically. Using various experimental rating conditions, we first scored 240 questionnaire items in their degrees of definitionally reflecting traits and/or adaptations. Next, we correlated these definitional ratings with the items' estimates of rank-order stability, consensual validity, and heritability—criteria often associated with personality traits. We found some evidence that items rated as more trait-like and less adaptation-like correspond to higher cross-rater agreement and stability but not heritability. These associations survived controlling for items' retest reliability, social desirability, and variance. The theoretical and empirical implications of these findings are discussed. © 2020 European Association of Personality Psychology  相似文献

From the standpoint of a Christian philosopher, heeding the teaching and exhortations of Pope John Paul II and previous popes, I examine three directions in which the recent philosophical debate has developed. In the last seven or eight years there has been 1) a renewed focus on the biological issue of when a human individual comes to be, 2) new arguments for the proposition that personhood is a characteristic acquired after birth, and 3) refinements of the early argument of Judith Thomson. Replying to these developments, I defend, on philosophical grounds, the pro-life position. I argue that a distinct, whole (though immature) human individual comes to be at conception, that he or she is a person, with full moral worth, from the moment he or she comes to be, and the mothers and fathers have a special responsibility to their children which entails (at least) that they ought not to choose to abort them. I conclude by briefly indicating, from the standpoint of Christian faith, why Christian philosophers should vigorously pursue this debate.  相似文献

As most studies report that the majority of sexual homicide offenders (SHOs) prefer to kill with their own hands, research has largely neglected to examine the choice of weapon by these offenders. The US Supplementary Homicide Reports show that although a large number of SHOs murder their victim using personal weapons (e.g. bare hands and manual or ligature strangulation), the majority use an alternative weapon (e.g. edged weapons, contact weapons, and firearms). The present study hypothesises that the choice of weapon is in part influenced by victim characteristics. To identify specific combinations and interactions between victim characteristics and the choice of a personal or edged weapon during the commission of a sexual homicide, a combination of exhaustive chi‐square automatic interaction detector and conjunctive analysis is used on a sample of 2,472 single‐victim male SHOs from a 36‐year period of Supplementary Homicide Report data (1976–2011). Findings show that SHOs choose their weapon according to some victim characteristics. Implications of the findings are discussed in light of police suspect prioritisation.
